working at different times

Part of my problems have started during June.
Since last summer. I have taken a addtional reponsablity at work. To this day wish I would not have taken it.

At the store i work at I work one day a week third shift. For a while I tought that I could take it and i would adapt. Before I work third I work first shift; then I go back in less than 6 to six hours.

Also though out the week I work work first and second shift.

i try to catch up some rest though out the week but part of me is active at night. Plue after work I feel tired all that time.

Working at some many differnt times like this has me worried at night; there are times when i worry when I work next.
